Abstract

PURPOSE:To operate a computer game machine in the same way as a joy stick with use of a mouse by applying no signal to the game machine before the moved variable of the mouse exceeds a fixed distance. CONSTITUTION:No movement information on a mouse 3 is given to the displacement deciding circuits 8a, 8b and 9 before either one of displacement outputs of plural digits connected to an exclusive OR circuit 7 has the value different from the displacement outputs of other digits. Therefore the circuits 8a, 8b and 9 never detect the movement of the mouse 3 before the moved variable of the mouse 3 exceeds a fixed distance. Thus the undesired movement information on the mouse 3 is never transmitted to a computer game machine as the control information. Then the input control equivalent to that of a joy stick (input device) is attained with movement of the mouse 3 when the computer game machine is connected to the mouse 3.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a detection sensitivity converter for a mouse, which is used as an interface for a mouse, which is known as a computer input device.

(Prior Art) A mouse is conventionally known as one of the input devices for computers (mainly personal computers). This mouse can be used to move the cursor on the computer's output screen by moving within a plane on the desk.
It has become a powerful input device in AD systems, etc.

A game machine (hereinafter referred to as “
In computer game machines (referred to as "computer game machines"), an input device called a joystick was often used as the input device, but a means for replacing the joystick with the mouse has not yet been developed.

(Problems to be Solved by the Invention) The inventor considered that by using the mouse as an input device for a computer game machine, it would be possible to improve the unity between the operator and the character 1 and others appearing in the game. The following problems were found when replacing the mouse with a joystick mouse.

That is, the mouse counts the movement of the mouse in two directions perpendicular to each other within an arbitrary plane such as a desk top, and counts the minute distance as one unit, and calculates the position after the movement by x-Y.
Because it has a structure that can be determined as a position in the coordinate system,
If such a count output is directly input to a computer game machine as a joystick signal, the movements of the character 1 and others will become minute (this is because the distance of 1 unit is considered a minute distance), and the game will not work. It was something that I didn't get used to.

Originally, when controlling the movement of a character or other objects using a joystick, it is controlled in eight directions, including the ±X direction, ±Y force direction, and a direction tilted at 45° to the X and Y axes when viewed in the X-Y coordinate system. Compared to this, a mouse detects movement in an infinite direction in the X-Y coordinate system and uses it as input, so its sensitivity is too high, making it difficult to replace it with a joystick. .

This invention was made in view of the above circumstances,
It has the following objectives:

(+) To provide a detection sensitivity converter for a mouse as an interface capable of connecting a computer game machine and a mouse.

(2) To provide a detection sensitivity converter for a mouse that can perform input control equivalent to a conventional joystick by moving the mouse when the mouse is connected to a computer game machine.

(3) Provide a mouse detection sensitivity converter that can change the sensitivity for detecting mouse movement.

(Means for Solving the Problems) A detection sensitivity converter for a mouse according to the present invention that achieves the above object is a device that converts the detection sensitivity of a mouse each having a displacement output of multiple digits in mutually orthogonal directions. and an exclusive OR circuit to which outputs of multiple digits are connected, excluding at least the most significant digit, for displacement outputs in each direction, and outputs and exclusive logic of the exclusive OR circuit. It is characterized by having a displacement determination circuit to which the output of a digit higher than the digit connected to the sum circuit is connected.

(Function) According to the detection sensitivity converter for a mouse of the present invention, among the displacement outputs of multiple digits connected to the exclusive OR circuit, one of the displacement outputs (the lowest digit among the multiple digits) is higher than the other. Since mouse movement information is not given to the displacement judgment circuit until the value differs from the displacement output of digits, the displacement judgment circuit does not detect mouse movement until the mouse movement exceeds a certain distance. . Therefore, for computer game machines,
Unnecessary mouse movement information can be prevented from being transmitted as control information.

By selecting a plurality of digit displacement outputs connected to the exclusive OR circuit, it is possible to set a distance at which the exclusive OR circuit provides movement information to the displacement determination circuit.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the state in which the detection sensitivity converter 1 for a mouse according to the embodiment is used, and is used as an interface between a computer game machine 2 and a mouse 3. The mouse 3 has traditionally been used as an input device for computers, and has a U mouse as shown by the arrow in the figure.
P-DOWN direction 4 and LEFT-RIGHT direction 5
Each has an 8-digit displacement output.

The detection sensitivity converter 1 for a mouse has the same circuit for the displacement output in the directions 4 and 5, respectively, and the UP-DOWN direction 4 will be explained below.

Figure 2 shows the circuit for UP-DOWN direction 4, and in the figure 6a, 6b, 6cm6h or up-DO of mouse 3.
This is an 8-digit displacement output in direction 4 of WN (6a is the most significant digit and 6h is the least significant digit). Further, in the figure, 7 is an exclusive OR circuit, ga, 8b is an AND circuit, and 9 is an inverter. The exclusive OR circuit 7 has four inputs, and among the 8-digit displacement outputs 6a to 6h, the intermediate displacement output 6C1
6d and 6e16f are connected. The output of this exclusive OR circuit 7 is connected to one input of two AND circuits 8a and 8b, and the other input of one AND circuit 8a is connected to the highest displacement among the displacement outputs. Output 6
a is connected, and the displacement output 8a is connected via an inverter 9 to the other input of the other AND circuit 8b.

Figure 3 shows the 8-digit displacement output 6a, 6b % 6c
... is a chart showing the level status of 6h (1 = high level, 0 = low level), and for each minute movement of 1 unit in the UP direction and DOWN direction, It changes according to a binary system, indicating that there are displacement outputs of 128 steps in each of the UP and DOWN directions.

Among these displacement outputs, intermediate displacement outputs 6c, 6d, 6
The exclusive OR circuit 7 connected to UP
High level (1) when the mouse 3 moves a distance of 4 steps in the direction of and 5 steps in the direction of DOWN.
Therefore, below each step, it becomes a low level (0).

As a result, the displacement determination circuit composed of the AND circuits 3a and 3b and the inverter 9 operates according to the truth table as shown in the following table.

That is, when the mouse 3 moves in the UP direction, the output of the AND circuit 8b becomes high level only when the mouse 3 moves four steps, and is given to the computer game machine 2 as an operation command signal. Similarly, when the mouse 3 is moved in the DOWN direction, the output of the AND circuit 8a becomes high level only when the mouse 3 moves five steps, and is given to the computer game machine 2 as an operation command signal.

The same goes for direction 5 of LEFT-RIGHT, the mouse 3 takes 4 (or 5) steps in the LIFT direction,
An operation command signal is given to the computer game machine 2 only when the computer game machine 2 moves five (or four) steps in the T direction.

Therefore, the displacement output 6 of the computer game machine 2 and the mouse 3
By updating a, 6b, 6C, . . . , 6h at regular intervals (all set to low level), eight-direction control signals similar to a conventional joystick can be given via the mouse 3. can.

The displacement outputs connected to the exclusive OR circuit 7 are not limited to 6C to 6f in the embodiment, but are, for example, 6b to 6e.
Then, the output of the exclusive OR circuit 7 can be maintained at a low level within the range surrounded by the dotted line in FIG. 3, and the sensitivity for detecting movement of the mouse 3 can be lowered. Therefore, for example, by making it possible to switch between the line connected to the displacement output 6f and the line connected to the displacement output 6b, and changing the connection digit position, it is possible to easily switch the sensitivity. be.

Furthermore, it goes without saying that the number of displacement outputs connected to the exclusive OR circuit 7 does not necessarily have to be four, and may be two, three, five, or six, excluding the most significant digit. stomach. Furthermore, one input of each AND circuit 8a%8b is not limited to connecting the most significant digit 6a during displacement output; If it is the upper digit (6b in the above example),
Similar operations are possible.

Furthermore, the displacement determination circuit is not limited to the circuit of the embodiment, and it is possible to obtain the same operation as the truth table described above by combining various logic circuit elements. Of course, by configuring as in the embodiment, the number of necessary elements can be minimized and the circuit can be made simple.

(Effects of the Invention) As explained above, according to the present invention, a motion command signal is not given to the computer game machine until the mouse moves or exceeds a certain distance. This has the effect of allowing you to operate a computer game machine in the same way as a conventional joystick.
